Description

Technical Field

[0001] The utility model relates to the technical field of wood pulp grid paper production and manufacturing, in particular to a temporary shutdown maintenance structure of a gluing device. Background Art

[0002] Wood pulp grid paper is a cleaning product commonly used in industry for absorbing liquids, removing stains and wiping surfaces. Typical wood pulp grid paper is usually a three-layer composite structure, the middle layer is a sparse grid material layer made of fiber material (also known as sparse grid cloth), the bottom layer and the surface layer are wood pulp raw material paper, which is composited through a special process.

[0003] Wood pulp grid paper has a wide range of applications and usage scenarios. It can be used in mechanical processing, automobile manufacturing, electronic production, aviation and other industrial fields, and is often used in automobile maintenance and servicing, hospitals, laboratories and other places and the sanitation and cleaning of instruments and meters.

[0004] Wood pulp grid paper can form a specific wrinkle foaming effect through bidirectional shrinkage, enhance flexibility, comfort, high absorption and stretchability, and have the characteristics of high strength, strong absorption, safety and environmental protection, non-toxicity, and no linting. It can replace the rags currently used to maintain the safety of the production environment, products, and personnel. In addition, based on the good water absorption, chemical resistance, tensile strength, anti-static, not easy to break, no linting, and reusability of wood pulp grid paper, it is an important cleaning material for industrial applications, greatly improving cleaning efficiency and quality.

[0005] In the prior art, the preparation of wood pulp grid paper is made by a two-step forming process, which separates the preparation of the scrim and the compounding of the scrim with raw paper: the first step is to use a special scrim production line to make the scrim (or directly purchase the scrim), and the second step is to use a special compound production line to compound the scrim with raw paper. However, since there are few manufacturers in China that can produce high-quality scrim, in high-end application fields (such as medical paper for surgical operations), it is only possible to import scrim finished cloth that meets strict quality requirements from abroad at a high cost, resulting in a high production cost for high-end wood pulp grid paper. For this reason, our company has now specially developed a wood pulp grid paper production equipment that does not require the use of scrim finished cloth. The equipment adopts the online laying and forming technology of the loose grid material layer. The loose grid material layer is formed as the loose grid cloth by the online laying of the yarn weft and warp. The equipment also adopts the specially designed pressing and compounding roller to press and compound the upper and lower layers of raw paper and the loose grid material layer coated with glue in the middle layer. After drying, the wood pulp grid paper is formed.

[0006] The above-mentioned wood pulp grid paper production process involves a process of gluing the online laid sparse grid cloth. In this gluing process, a gluing device with a transfer roller, a gluing roller and a gluing roller is used to gluing the sparse grid cloth. The specific gluing process is to arrange the online laid sparse grid between the upper and lower gluing rollers and the gluing rollers, transfer the aqueous glue to the gluing roller through the transfer roller partially immersed in the glue pool, and use the pressure between the gluing roller and the gluing roller to evenly apply the glue to the online laid sparse grid cloth.

[0007] However, after the water-based glue is exposed to the air, its internal moisture will evaporate rapidly in a short period of time. If the wood pulp grid paper production equipment is temporarily shut down due to various reasons, when it is restarted, the transfer roller, glue coating roller and glue pressing roller in the gluing device that are exposed to the air will evaporate within tens of seconds. The moisture in the glue on the surface will cause the glue to solidify on the roller surface. The operator needs to perform special cleaning and maintenance before the production can continue, which increases the maintenance workload of the equipment and reduces the efficiency of wood pulp grid paper production. In addition, due to the difference in skills of the operators, there is a possibility that the solidified glue will not be cleaned thoroughly when manual cleaning is used, which will affect the quality of subsequent gluing. Utility Model Content

[0008] In order to solve the above problems, the utility model proposes a temporary shutdown maintenance structure of the gluing device, which aims to realize the rapid activation of the gluing device after the temporary shutdown, reduce the maintenance workload of the gluing device, improve the efficiency of wood pulp grid paper production, and ensure the production quality of wood pulp grid paper.
